PTH and gastric squamous cell carcinoma: Raju et al. [11] reported a case of a patient with squamous cell carcinoma of the stomach and hypercalcaemia; in their opinion, the hypercalcaemia of malignancy is due to ectopic production of parathyroid hormone (PTH) by the tumor; however, there was no hypercalcaemia in our patients; on the contrary, we observed hypocalcemia in nine patients; in addition, we also observed hypoalbuminemia in 9 patients; we hypothesized that patients with hypocalcemia or hypoalbuminemia were related to inadequate intake and excessive consumption of the disease.
